Be it known thatfl, :LEWIS :'DoivrAN,.a .citizen..of..the.United States of Amerlca, and

l.residentoif y.East Syracuse.. intthe .county'k of Onondaga, in the. State ofNew York, have vinvented, .new .and `useful .Improvements in Note-Sheets .for SelffPlaying .Musical AIn- .struments, of which -the following, taken s in connection .with the accompanying drawings ,v is. a full... clear, and Vexact description.

y This inventionrelates tocertain. improvements `in note ysheets .for .self-playing musical .instruments .and `is, adapted to bel used more,- particularly in: connection Awith-aaasuitf ablen selective Vapparatus not shown. for. playing one or more parts,.asoreXample-the solo part of a musical `compositionlwvith greater...force i or emphasis .than .the remaining p arts.Y .These Inote .sheets are `usually made .of uniform. orstandard .width ...capable `of receiving a number of rows vofxnoteperforatons..corresponding to `.an .eighty-eight Y note- .player, leaving arelativelyfnarrow marginal spacenear oneorbothfedges, v.

.The .mainobject .isvto providethe V.note i sheetwvith a relatively.smallernumber of rows ,Ofselective gperforations -capable .of .automatically causing Vthe .individual notes of. any one or more Vparts of..a;musical selection within Athe range .ofthe player V.to be played with ,greater .force or emphasis than theremainingparts, n

The specific` .objectis` to. enable..these.-selec tive perforations to. be placedl ina`relatively narrow space on .the ordinary. note .sheet-of an,eighty-eightnoteplayer without in `any way interfering with thenote perforations forthefullrange: of the player. n

the perforations in the lines 1-, -Q, -3, and so on may be termed the .octaveselecting pertorations, While those 1n the other four roivs A, B, C, and D, may be termed the group-selecting perforations. These several rows of selective perforations are adapted to cooperate with suitable ducts of a tracker bar. not shown, for controlling the operation of suitable pneumatics also not shown. Portions at least of theseselective perforations run simultaneously with the note perforations representing the solo or other part which is to be played with greatest force or emphasis, and for this purpose, the selective perforations are so placed upon the music sheet that their advance ends are in amproxiinatelyv the same transverse line as the corresponding ends of the note perforations representing' the notes which are to be emphasiZed,-that is the advance ends of the selective perforations are adapted to recister with their corresponding' ducts at about the same time, or a little before, the corresponding ends of the note perforations register with their tracker ducts.

The position of the octave-selecting perforations in any of the several lines 1-, 2, -3 and so on4 depends upon the octave or octaves in which the solo or other part to be emphasized is played. and conseuuentlv depends upon the position of the note perforation or perforations representing such solo or other part, so that if one or more measures of that part is played in one octave. the selective line of perforations representinq that octave Will run simultaneously with the note perforations in such measure or measures. If the solo part should run into another octave, the selective perforations for that octave would run simultaneously with the note perforations renresentiuo' the notcs in that octave, While the first line of octaveselectine perforations Vwould terminate at about the beeinnine' of the second line of octave-selectin@ perforations. It, therefore. follows that if the notes to be emphasiaed should run through the entire ranee of a seven octave player. it would reduire the use of seven rou's of octave-selecting perforations. but no more.V In like manner, the group-selectino perforations for any group of notes, either of which of that .frroup is to he eniphasi7ed. heoin at or sliehtlv before the beginninsr of the note perforation in thev sheet representing such note. and when the note sheet is used with reed or continuous tone instruments. the perforations run simultaneously and continuously with the note sheet aperture representing such note, as

` group perforations'for any particular note which is to be emphasized are of substantially the same length as the perforations representing such notes.

In the use of this note sheet one or more of the group-selecting` perfor-ations must run simultaneously with one or more of the octave-selecting perforations in order that any note of a particular group may be plaved in the proper octave. although it is evident that the position of the group-selecting perforations may change from line to line accordinn' to the chane'e of notes as represented bv the corresponding note perforations, While the octave-selecting perforations may run continuously in a single line so long as the notes to be played are Within a single octave.

That I claim is:

1. A note-sheet having octave-selecting perforations and group-selectin@ perforations runningr simultaneously with certain note-perforations- 2. A note-sheet having notemerforations representing different parts of a musical composition. said sheet being provided with oetavesselectinler perforations and group-selecting perforations running in parallel lines simultaneously with the note-perforations representing one of said parts.

3. A, note-sheet having note-perforations remesentinn' the parts of a musical composition. said sheet being provided with an octaveselectinev aperture, and a cooperative group-selecting aperture occurring simultaneously with each other and with the advance end of one of the note-perforations.

4l. A note-sheet having note-perforations representing different parts of a musical composition. said sheet being provided with octave-selecting' apertures in different lengthwise lines. and coperative group-selecting apertures also arranged in separate lengthwise lines and running simultaneously with portions of certain note-per forations.

In Witness whereof I have hereunto set my hand this 7th dav of September. 1915.
